Identify the nature of each substance: Determine if each substance is a pure substance or a mixture.
Classify pure substances: Pure substances can be elements or compounds. Elements consist of only one type of atom, while compounds consist of two or more types of atoms chemically bonded together.
Classify mixtures: Mixtures can be homogeneous or heterogeneous. Homogeneous mixtures have a uniform composition throughout, while heterogeneous mixtures have a non-uniform composition.
Apply classification to each substance: For example, water is a pure compound because it consists of H2O molecules. Ice is also a pure compound because it is the solid form of water.
Determine the type for coffee and carbon: Coffee is a mixture, typically a homogeneous mixture, because it consists of various compounds dissolved in water. Carbon, in its pure form, is an element because it consists of only carbon atoms.
